ICOT, Thank You.
Yes, I still await that answer; Dina Dmalchusa Dina (for some reason) has always been a halachic topic of interest to me. I’d love to hear another perspective.
BTW I cannot seem to find the original thread this was discussed under. I mentioned that in many secular legal matters, DDD is inapplicable. (Such as capital punishment, since you brought it up, as it is enforced by secular courts without any input from beis din.)
Another interesting thing about DDD is that it is inapplicable in Eretz Yisroel (as discussed in the famous Ran in Nedarim.)
P.S. You point about calling chumras (and other disliked halachas — most notably tznius) “Talibanization” is something I’ve been yelling about for a long time here!
